I use a personal account. I can only get a business account where you can't transfer between different accounts, I would have to go into the branch every time I wanted to do something.
I have 4 seperate accounts with the same bank.
1) For customers to pay in
2) For business use
3) For house bills
4) For me
So long as you don't mix up the accounts its easy. 1 for money in, another for money out for the business. I'm going to set up a savings account for tax / equipment etc when I move.
